JOINERS PLANE.

Specification of Letters Patent No. 5,620, dated June 6, 1848.

To all whom it may concern Be it known that I, VILLIAM A. COLE, of NewYork, in the county of New York and State of New York, have invented anew and Improved Plane for Planing Curve or Level Surfaces; and I dohereby declare the following to be a full, clear, and exact descriptionof the same, reference being had to the annexed drawings, making a partof this specification, in which- VFigure 1 is a side elevation of theplane. Fig. 2 is an end View.

Similar letters refer to similar parts, in both figures.

The nature of my invention, consists in an improvement in theconstruction of the plane, by which I am enabled to curve the face ofthe planeeither concave or convex, and regulate the face of the saidplane so as to plane various curves with the same plane.

In` making my improvements I take an ordinary plane, with-the planeirons, &c., as usual, I then cut a convex face upon it as seen at (cr-).To the face thus prepared I attach a plate of inetal (c), at the center,the length and width of the plane; at the center there is a slot cutacross through which the edge of .the cutting iron may pass. At each endof the plate (c) there is a slide (d) connected, which passes up againstthe front and back of the plane, beneath a plate of brass, space beingleft sufficient to allow it to pass up and down.

In operating this plane, the face plate (c) is Iset to the desiredcurve, by pushing the pieces (d) down, these are then confined in theirplaces, by a screwfe) upon the ends of the plane as represented. It willbe seen that concave and convex surfaces can be planed by thisinstrument, and that it can be adjusted to any desired curve, as setforth and described above.

7hat I claim asmy invention and improvement, and desire to secure byLetters Patent, is

The adjustable metallic spring plate, secured to the face of the planefor the purpose of planing with one plane, various curves either concaveor convex, substantially as herein described and set forth.
